Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information
Additional information
Studies are available for toxicity to daphnia, algae and activated sludge microorganisms. Public studies are available for acute toxicity to fish both giving experimental and QSAR values.
The 96-hour LC50 of hexyl acetate to fish was found to be 4.4 mg/L. Two public domain studies were found which assessed the acute toxicity of hexyl acetate to fish. Eldred et al. (1999) gave an experimentally determined value for the acute toxicity to fish of 4.4 mg/L. Similarly, Veith et al (1985) found that the LC50 was 4.4 mg/L. As such, a weight of evidence approach has been taken and the lowest relevant EC50 for fish is 4.4 mg/L.
The 48-hour EC50 of hexyl acetate to Daphnia magna was determined to be 9.1 mg/L.
The 72-hour EC50 of hexyl acetate to algae was found to be 12mg/L and the NOEC was found to be 2.7 mg/L.
The 3-hour EC50 of hexyl acetate to STP microorganisms was found to be 100 -1000 mg/L (100 mg/L used for PNEC derivations as a conservative assumption). The NOEC was 100 mg/L.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
